The Scanner class is defined in java.util package that is used to take input from the user. The Scanner class provides the following two methods to take input from the user.

The nextLine() method reads the input till the line gets terminated and shifts the cursor to the next line. The syntax of the nextLine() method is:

Syntax:

public String nextLine()

The method does not accept any parameter. It returns the string that was skipped. If the method finds no line to read, the method throws the NoSuchElementException.

import java.util.Scanner;

public class StringInputExample

{

public static void main(String argvs[])

{

// To hold the string input by the user

String str;

// creating an object of the Scanner class

Scanner scnr = new Scanner(System.in);

System.out.print(“Enter a string: “); // invoking the method nextLine()

// to take input from the user

str = scnr.nextLine();

// for new line

System.out.println();
